Application led May 27,

stated which may be readily formed from sheet metal, so a's to be produced at small cost. A further object is to provide a. heater in which the walls of the body or casing are prevented from becoming heated, lthus permitting the heater to be readily handled and, `if desired, to be placed adjacent to the wall of a room without danger of setting reto the saine. A .further object is to provide a heater in which'the products of combustion may be collected in a suitable hood andpermitted to escape through a flue, this hood acting as a supplemental heating device for heating air circulated about the hood. Further objects will appear trom'the detailed description.

ln the drawings z- Figure 1 is a front view of a heater constructed in accordance with my invention;

Figure .2 is a central horizontal sectional view through the heater;

Figure 3 is a central vertical sectional view;

Figure 4 is a' section taken substantially on line H of Figure 3;

Figure 5 is a fragmentary detail of the means for securing the locking plate.

rEhe body of the heaterincludes a bacl; plate 1 which 'is secured at lits ends by seams 2, or in any other suitable or prei'erred manner, tothe rearward edges or' side plates o. Each of these side plates includes an outwardly and forwardly inclined element 3a :ti-cin the forward edge of which extends an element la parallel with the rearward portion or' the plate. The forward portion ot each element e is formed to provide a cylindrical roll or post 5 which serves to materially reinforce the front of the structure while presenting a neat appearance, each of these rolls khas at i921. l serial, no. 473,096.A

its lower end a disc 6 o1" greater diameter than the roll, these discs acting, with posts 5, to provide toot members for supporting the front of the casing.v r disc 7 is secured in the top of each postand is provided with anornainental knob Sto give a neat finish tothe posts;

A lower front elements la of 'side plates 3, this plate'being inclined upwardly and inwardly of the body or casing 1. .v An upper front plate 10,

A CORPORA-- plate 9 is secured between which is also inclined upwardly and inwardly'of the body is secured at its lower edge'to the upper edge of plate 9.A The upper edge ot' vplate 10l is secured to the forward edv'e of a sheet metal 'supporting plate 11 of channel cross-section (Fig,A which is also securedto black plate 1, this` supporting plate occupying the space between side walls 3V and back plate 1 and plate 10. A top plate 12 is secured over the upper edge or the baclrplate l, and to the upper edges of side plates 3 which are extended above the posts 5 for this purpose.

has its upper wall vdisposed substantially' parallel with top pla-te`12. The end walls 14: of'this hood are spaced away from side walls 3 so as to leave spaces 15 which per init air flowing through slots 16 provided through plate 1'1 yto flow upwardly between side walls 3 and the end walls 14 or" hood 13,v

this air circulating about the ends of the hood and through thevspace 1,6 between the hoodl and top plate 12, and then escaping through the 'open `work 12v provided in element 12a of top plate 12. In this manner the hood serves as a supplemental heating means, the hood itself ,being heated by the products 'fof combastion which escape into the hood in a ni'auner to be described. Itis also to be noted that the cool air which enters 'the bottoni ot the casing through openings 17 provided in side walls 3 and baclr wall 1 for this purpose, during its upward flow serves to effectively cool the side walls of the casing so as to prevent heating thereof, as well as the lower portion of 'the back wall.

2li {irebaclr 18 oi" clay or other suitable Y This top plate l 12 is extended forwardly and downwardly refractory material is supported at its lower end in a sheet metal channel member 19 which is secured upon the upper face of plate 11. The upper end of back 18 is secured by sheet metal angle brackets 2O secured to the inner face of back plate 1. The body of this back is disposed in parallel spaced relation to plate 1 so as to leave an air space 21 between this plate and the bach. The air which entersl space 21 through slots 1G flows upwardly through this space and cooperates with bach 1S, whichv acts as a. heat insulator', to effectively,l prevent heating of the back plate, a` portion of this air flowing upwardly about they ends of hood 13, as previously noted, through the spaces 15 provided between the back and side walls and lateral extensions 22 of rebacl; 1S, these extensions projecting forwardly of the body of back 1S and fitting snugly against end walls 3. 1n this manner the casing is maintained in a comparatively cool or unheated condition thus permitting the heater to be readily handled, or to be safely placed adjacent to a wall or other structure. The extensions 22 of irebaclr 18 co-operate with the body of the back to provide an elongated rectangular recess for reception of a plurality of tubular members or radiants 23 formed of clay or other suitable refractory material, the front wall of each of these. radiante being of open or lattice work construction. rest upon the upper face of plate 11 and are held in alignment with rectangular openings 2st provided through the plate by front flange 19"l of channel member 19 and vflanges 25 provided at the forward edges of openings 24, rlhe radiants 23 have their upper end portions confined between the bight portion of a U-shaped holding member 26 formed of wire and the body of fireback 18, the arms 27 of member 26 being slidable through the top plate of hood 13. Downward movement of member 26 is positively limited by rectangularly disposed lingers 28 provided at the upper ends of arms 27, and this member is normally pressed toward the radiants by an upwardly and inwardly in clined flange 29 provided at the inner edge of a channel element 30 formed at the lower edge of a downwardly and rearwardly inclined locking and reflecting plate 31 extending froin the lower edge of hood 13, this plate and the hood and element 12b of top. 12 being all secured together by means of screws passed through the same and nuts threaded onto these screws, or in any other suitable or preferred manner. The plate 231 extends the full width of the body or casing of the heater and is secured to the side walls at each end by means of an angle member 32 the horizontal arm of which is secured to the central portion of The lower ends of the radiants channel element 30, the 'vertical arm of member 32 being riveted or otherwise secured to the adjacent side wall 3. The arms 27 of member 2G fit snugly through the top of hood 13 and co-operate therewith to hold member 26 in vertical adjustment.

This provides simple and el'licient means whereby the radiants may be readily inserted or removed. as desired.

'A gas burner 33 of any suitable or preferred type is supported within casing 1 below plate 11. The burner shown includes a sheet metal boe y or casing Bat which is provided in its upper wall with. a z .iliiirality of rectangular series of perforations 35 disposed in alignment with the respective openings 24 through plate 11, anda mixing tube 36 for admitting a mixture of gas and air into casing 34. rfhe mixture of and air flows thrcughthe openings and ignited in the usual manner. producing` an intense heat which serves to quickly heat the radiants to incandescence. As any other suitable or preferred type of burner mayY be employed than that illustrated herein, and as the burner illustrated forms the subject matter of a separate application filed by me, it is not thought necessary to give a more detailed description or illustrate more fully the burner disclosed. The radiants 23 are en closed by the irebaclt 118.. the lateral eXtcnsions 22v serving to effectively p event heating of side walls Il and cooperating with the inwardly inclined elements 3 for reflecting forwardly of the heater the heat generated in the radiants 23. The upwardly and inwardly inclined platesl 9 and 1l) and the downwardly and inwardly inclined element 12" of top 12 and locking and reflecting plate 31 co-oporate with elements Il of the side walls to reflect the heat generated outwardly and forwardly of the heater so as to obtain the maximum heating effect.

By the structure disclosed and above described provide a heater the body or casing of which maybe readily constriu-ted from sheet metal and can, therefore, be readily produced at small cost while being of substantial construction and presenting a neat appearance. 1n addition` l provide simple and efficient means whereby the walls of the heater are effectively cooled so as to permit the heater to be safely handled at all times. rThis is accomplished by the cool air which enters the lower portion of the body or casing through the openings 1T. a supplemental supply of cool air entering the casing 'through the open work 23T provided in plate for this purpose.

As will be clear from Figure the products of combustion escape from the upper ends of radiants 223 into tne hood 13, these products escaping from the hood through an escape opening provided in bach wall 1, a collar 3S being secured to the outer face of the back wall about this opening and providing means adapted for reception of-suitable piping for conducting the products of combustion to a flue or chimney. I thus obtain a maximum heating effect while avoiding the escape of the products of combustion into the apartment or room being heated.

Preferably, though not necessarily, I provide a wire guard 39 positioned in front of the radiants, this guard being provided at its upper end with a rod 4:0 the ends of which fit tightly into sleeves 4l secured through elements 3R iit tightly about the ends of the rod and provide friction locks for holding the guard in raised position when it is desired to remove or replace any of the yradiants. Normally, as will be understood, the guard is in lowered position.

It may be found desirable, by experience, to resort to changes in details of construction and arrangement of parts of the invention, and I intend to include all such variations, as fall within the scope of the appended claims, in this application in which a preferred form only of my invention is disclosed.

What I claim is l. In a heater of the character described, a casing including side and back plates, lower upwardly and inwardly inclined front plates connecting said side plates, a supporting plate connecting the upper one of the front plates and the baclr plates, a refractory backing member mounted on said supporting plate and tting between the side plates, said backing member being provided with lateral forwardly projecting extensions, radiante mounted on the supporting plate between said extensions. means for heating said members, a lhood above the radiants, a downwardly and inwardly inclined reflecting and lockingplate extending from the forward edge of the hood to the upper ends of the radiants and provided on its lower edge with a resilient element, and a member confined.

between said resilient element and the outer faces of the radiants for securing the latter in position.
